Although not a matter here at all of breach of contract, but more akin to sticking to the contract, how do most organisations generally view and / or take it (if it's really an issue at all) if a long standing, good and high performing employee wishes to do a good job, stay put and essentially perform the same level role, not act up, not take on any more or additional responsibilities and simply not apply for any internal roles that may become available?       

Are there unofficial expectations that with over time and experience, most people should move up or on, and what is the general view if someone is going against the grain so to speak by choosing to firmly 'stay put' yet all the other employees are not?

It's not of course a capability or a performance management issue as they are performing well and meeting the requirements of their current role within the overall context of their contract of employment and job description, but basically just wish to do the same job.
